сжатие и склейка .vob-файлов
Можно - VirtualDub. Сыслки на него в форуме уже мелькали, да не стоит забывать о lorien. :-)
я не знаю, как там делать надо.
по идее, сначала открыть эти файлы? но они не открываются...

Тебе надо поставить кодеки. (Возможно Nimo поможет)
какие?
Дай ссылку на файл.
там куча .vob файлов
Для VirtualDub я кодеков не нашёл, зато нашёл две другие проги: TMPGEnc и DVD2AVI.
Но с ними надо разбираться. TMPGEnc вроде у меет только в MPEG1/2 кодировать (нужно ещё поставить , DVD2AVI - скудна в настройках. IMHO: лучше попытаться найти кодек к Virtual Dub.

спасибо.
будем искать и пробовать

Понаписал то а ...
VirtualDub тут не нужен, elecard MPEG2 decoder (m2v_codec.exe) тем более.
TMPGEnc вполне хватит чтоб сделать MPEG2->MPEG1.
Если в divx надо, то DivX Сodec.

Что значит DivX Codec? Это так софтина называется?
И чем тебе так VirtualDub не угодил?
P.S. TMPGEnc без m2v_codec.exe не откроет файлы MPEG2.

Вобщем самый простой способ: возьми DVD2AVI, открой в нем свой MPEG2 файл, сделай Save AVI,
когда спросит в какой формат жать выбери DivX Codec.
Предварительно у тебя должен стоять нормальный DivX, который не только енкодить умеет, но и кодить, у меня к примеру стоит DivX5.0.2 от DAMN

уже почти сделал 
Чем делаешь то?
dvd2avi
Т.е. ты без нас разрюхал DVD2AVI? :-
Вовка, судя по твоим предыдущим постам, твоя помошь не потребовалась бы, если не знаешь, лучше просто помолчать.
не знаю.
мне вот только не нравится, что он звук отдельно пишет. Может знаете, как его в avi-шник запихать?

virtual dub'ом - если есть звуковая дорожка, сжимаешь ее в mp3 и цепляешь к avi/
могу дать версию, которая может
может что? музыку впихивать ?

More new things added.
1) 2pass support for avi saving.
2) Added crop-resize engine by Ogo.
3) More options in MP3 encoding dialog.
4) MP3 output can be mix with video in AVI. (I can't recommend do this, Video and audio have't good iterleaving, some times it can be unsync,no way to solve this with current code structure).
5) DTS track can be extracted.
6) P4 iDCT by Dmitry Rozhdestvensky. Only in exe, NOT TESTED!.
7) Normalization is back.
8) Added possibility log switching between FILM<->NTSC.
9) Old Bug fixed and new added. (It become maze of flags, if {}else{}. I think most of code will work fine, but... )
Next releases will be bugfix only.
Development DVD2AVI 2.0 is pending now. I not found tool that can do 100% accurate IVTC in hard cases, so i try make such tool, this my top goal.

расшарь тогда, пожалуйста.
2 : ты div2avi сам юзал? какие параметры задавать при кодировании, в частности, для DivX 5.02 ? просто при просмотре во время кодирования заметен большой интерлейсинг. Чем его убрать? и еще: что происходит на первом и втором проходах при двухпроходном кодировании (для DivX) ?

На моем компе кодить в DivX нереально,
вот попроси Антона - он тебе либо так расскажет, либо скажет что почитать надо.
Вот то что я читал когда-то, может теперь устарело правда:
GENERAL PARAMETERS
-pass
In this mode, the encoder will aim at making the average bitrate of movie close to specified value, retaining more data for low-motion scenes and losing more information in fast-motion scenes.
1-pass quality-based mode
In this mode, all frames receive the same amount of compression, without regard to their complexity. While it is not the best choice for making archives, it is a good idea to use this mode when preparing content for future editing. It guarantees the preservation of quality in all frames.
2-pass variable bitrate mode explained
In this mode, the encoder will try to make the subjective quality of the stream constant, and simultaneously make the complete stream size close to the number you specified. If you want to encode a 2-hour show that it fits on a 650 Mb CD, use this option.
Operating in this mode is most complicated, because it requires the source to be processed twice. 2-pass encoding is independent from any application you may use for encoding. It can be used with any program. However, it needs to use an external file on your hard disk to temporarily store encoding data.
2-pass, first pass
First open the encoder configuration dialog box (in your encoding application like virtualdub choose "video | compression" highlight "DivX 4.0x" and press the configure button). Then go to the "general parameter" section use the "Variable bitrate mode" pull down menu and choose "2-pass, first pass." During this pass the encoder ONLY analyzes the source and then creates a log file with information about the frames. The "Log file" field in encoder configuration dialog must point to the place where encoder has write permissions (you'll need about 250 kb of disk space for each 1 minute of video. A log file can be tens of MB's). Start 1st pass process. The encoding program will then create an unplayable AVI file and write the log file in the root of your "C" drive.
2-pass, second pass
When it's finished, return to the configuration dialog and select "variable bitrate mode" --> "2-pass, second pass." Start encoding (the source video must be the exact same one!). At this time, the encoder will read the log file that was created in the first pass and writes the real VBR AVI to the root of the "C" drive, or to another location you specified.
It is best to use the same "performance/quality" setting for both passes, but it is not an absolute requirement. Don't use performance/quality mode of "fastest" for either of two passes. You can also use different values for "bitrate" in first and second passes, but if they differ by +50% or -50% the encoder may not achieve the file size you want.
Performance/quality
The settings are: Slowest, Slow, Medium, Fast, and Fastest. These let you decide whether you want the encoding to be done fast or to crunch everything to the smallest possible size. "Fastest" mode is optimized for real-time video capture. This choice is recommended for use with "1-pass quality-based" bitrate mode. "Slowest" mode with "2-pass variable bitrate mode" is good for making video archives. The default value is "slowest".
Output Video Bitstream
It shows the current kilobit/second. You can manually or use the slide bar to input a stream value between 0-6000 kbps when using 1-pass encoding.
Maximum key frame interval
This is the maximum interval between the places to which you can seek in resulting file. The DivX encoder will insert a key frame every time it detects a scene change. However, long intervals between scene changes are possible, and when they occur, the encoder automatically inserts keyframes with specified frequencies. The default value is 300, which corresponds with one keyframe at least every 10 seconds in a 30 fps stream.
Max CPU
This sets the minimum and maximum level at which CPU time used by the encoder, to give some time to other tasks or to reduce processor temperature, for example. By default, it is turned off. If you have a really fast enough processor (700 MHz or faster) turn it on.
Deinterlacing
Video streams captured from TV or VCR in high resolutions usually contain "interlacing" artifacts. For example, maximum allowed height for NTSC is 480 lines at 30 frames/second. However, the actual television signal has a frequency of 60Hz and only 240 visible lines. Thus, captured streams will contain interleaving lines from two subsequent "fields," which have different positions in time.
The good thing about deinterlacing inside the encoder is that it's done almost for free. The most popular video processing applications include deinterlacing filters, but they can eat up to 15-20 percent or more of the time. In contrast, deinterlacing in the encoder takes no more than 1-2 percent of CPU power. The default setting for "Deinterlacing" is "off."
Do not use deinterlacing inside the codec if input stream was resized or otherwise preprocessed in some way. If you want to do complex filtering of interlaced streams, always use external deinterlacing and put deinterlacing filter first in the pipeline.
DECODING PARAMETERS
Post-processing
The post-processing algorithm consists of the deblocking and the deringing filters. Post-processing is a CPU-intensive process, which sometimes takes longer than decoding. You may not want to post-process, especially if you prefer the un-post-processed image, or if your PC is not powerful enough. To cater to users' post-processing preferences, 6 different levels of post-processing have been defined. At the minimum (level 0 no post-processing algorithm is used; at the maximum (level 6 every clever algorithm is tried to enhance the appearance of your frames. The human eye is less sensitive to the chrominance components of the video signal and more sensitive to the luminance components. For this reason, only the luminance plane is processed at lower post-processing levels, while higher levels activate the same algorithms on the chrominance planes. The post-processing algorithms used are activated in the following order: deblocking on luminance planes, deblocking on chrominance planes, deringing.
You can adjust postprocessing level in two ways. Use the slider in the configuration dialog of DivX DirectShow filter (which can be accessed from Windows Media Player window while playing) or in configuration dialog of encoder DLL. Both sliders do the same thing.
1 PASS ENCODING PARAMETERS
MAX and MIN Quantizers
The Quantizer is the most important parameter in video encoding. Without going into detail, quantizer controls how fine the encoder codes the video sequence. The rule of thumb is: for the same frame, smaller quantizer ==> better quality, higher bit consumption. Larger quantizer ==> lower bit consumption, inferior quality. Adjusting the quantizer operates the rate control. To balance the qual
